Re: [Banana] Charter

[<[e-mail]>]

Hi,

the document expired in May. It was written quite a while ago in order to support the initial discussions around bandwidth aggregation based on one use case. We already said at that time, that the scope of BANANA should be broader and not focus only on two specific technologies (like DSL/LTE). With the existing charter I see the draft more in a "historic" context and clearly not as a potential working group document.

Regards

Nic

Ok. Lets quickly review the PS document that was used for this discussions, draft-zhang-banana-problem-statement-03.txt ("Problem
Statement: Bandwidth Aggregation for Internet Access²)

"
1. Introduction

   Use cases of BANdwidth Aggregation for interNet Access (BANANA,
   a.k.a., Hybrid Access) are described in the Technical Report [TR-348]
   published by Broadband Forum: by providing Hybrid Access, Service

³

Your use-cases are what BBF has defined per your PS. I assumed its clearly about DSL + LTE aggregation, that is driving this work. Now, if the argument is we need DSL + SATRAN, please point me to one RG that has support for DSL and Satellite, or a deployment where an RG uses Wi-Fi as a WAN link. Sure, I also saw the comment from Margaret that "one person on this thread mentioned wanted to aggregate two WiFi links, another person has talked about aggregating VPN links².  I wonder, if we have we made it so easy that we can create IETG WG¹s so easily, based on such individual wishes, with no details on how and where its used. Its well understood that link-aggregation has value and nothing new there. But, please present very specific use-cases beyond BBF use-case.





Regards
Sri
